Well, just to add my 2 cents, I think that sub-MOA rifles are more commonly available today than they were 30-some years ago when I started shooting. Part of the difference lies in the greater accuracy potential of modern machining and tooling, and another part lies in the quality of the ammunition we have available today. For certain, factory ammo is vastly better in quality now -- and I can assure you that it was no great feat for even yours truly as a 14-year old kid to crank out handloads that ran circles around factory fodder. These days, it's not so easy to do that. Not impossible, for sure -- but there's plenty of factory ammo that will shoot sub-minute in a quality barrel attached to a quality rifle.
Now, is sub-MOA terribly common in a sporter weight rifle? It may not be the statistical norm, but the average is certainly closer to 1 MOA than to 2 MOA if it's properly bedded and care is taken in the reloading. But look at what we have to work with today -- much more uniform bullet jackets, premium quality seating dies that can reduce run-out to a couple thou even in non-uniformed brass (which, by the way, is generally more uniform than it used to be), and a vast array of powders. It would be a real eye-opener for some to look back at the Sierra, Speer or Hornady manuals from the late 70's/early 80's, and realize how many more variables we have to play with these days. And let's not forget the quality of the glass we have now, too. It's simply amazing, for example, how groups tend to shrink on any rifle when you mount a Nightforce or something similar on top of it with max magnification north of 20x...
As I think about the bolt action rifles in my rack at the present time, there are 3 heavy barrel target rifles -- there's a stock Rem 700 VS that averages (5 shot groups) around 1.25 MOA. Then there's a trued Rem 700 with a Hart barrel that averages well under 0.5 MOA, and has produced many groups in the 2's, and even a few in the 1's. And then there's also a PGW Coyote that shoots around 0.6 MOA. Those really are the results I get, and they're reproduceable.
When it comes to sporter weight hunting rifles... Well, things change a bit. Of the several I own, there are 12 that I shoot regularly enough to be truly familiar with. The Rem Model 7, CZ 527 (x2), Weatherby Vanguard, S&W 1500, Ruger 77 and Ruger RSM are NOT sub-MOA rifles. The average here is closer to 2 MOA than it is to 1. All but one of them them, however, will keep the shots inside 2 MOA with their favourite handloads.
At the same time, however, the Tikka T3 and the HS Precision PHR will average right around 1 MOA very consistently.
And then there's the Rem 700 BDL, Sako A1, and Browning BBR (with a Lilja barrel) that absolutely shoot sub-MOA very, very consistently.
So what is that -- of the sporting weight rifles that I use most often, 25% of them are honestly sub-MOA rifles.
I don't know what the norm is these days, but I think that's probably fairly representative of what's out there. In a nutshell, I think it's reasonable to lust after a 1 MOA sporter, presuming you're willing to buy quality in the first place and are prepared to go through a few before finding one that's a keeper. In a heavy barrel, however, I think it's reasonable to expect sub-MOA performance as a must-have.
OK, that was probably more than 2 cents...
